Description

[Detailed Description of the Invention] [Technical Field of the Invention] This invention relates to an air conditioner, and particularly relates to an improvement of a damper opening/closing device.

[Prior art]

Figures 10 and 11 are, for example,
FIG. 154550 is a side view showing the conventional damper opening/closing device and an explanatory view showing the main operating parts of the damper part.
A partition plate 35 is provided to partition the indoor side 4 and the indoor side 5, and an opening 15 communicating between the indoor side 4 and the indoor side 5 is formed in the partition plate 35. A plurality of dampers 36 for opening and closing the opening 15 are provided in the middle. A wire 39 supported on the indoor side 4 via a support fitting 37 and a fulcrum 38
It was configured to be opened and closed by a lever 40 provided at the end of the door.

In the damper opening/closing device configured in this manner, when the lever 40 is slid from the outside, the fulcrum 38 on the lever 40 side and the supporting metal fittings 37 and 38 adjust the position of the wire 39 and smoothly apply an external force to the damper 36. transmission, and the damper 36 could be opened and closed freely.

However, such a damper opening/closing device has disadvantages such as a large number of parts such as supporting parts, time required to assemble the opening/closing device such as wires, and the damper opening/closing operation cannot be performed reliably. .

[Summary of the idea]

This invention was made with the aim of improving the above-mentioned drawbacks, and provides a damper opening/closing device that improves the operability of opening and closing the damper and simplifies the assembly work.

[Example of idea]

One embodiment of this invention will be explained with reference to FIGS. 1 to 9. 1 is an integrated air conditioner main body, 2 is a base, 3 is an electric motor for blowing air installed approximately in the center of the base; Indoor blower 6 on the shaft
is attached, and in front of this blower 6, a partition plate 8 on which a suction bell mouth 7 is formed facing the outdoor side 5 is erected and fixed. Reference numeral 9 denotes a fan casing of the indoor blower 6 made of a heat insulating material, which is formed so as to wrap around the indoor blower 6, and upper casings 10 are arranged above and below the center of the blower electric motor 3.
and a lower casing 11, and the upper and lower casings 10, 11 are each provided with partition walls 12, 12 and air passages 13, 13' that partition the indoor side 4 and the outdoor side 5, and a partition plate 8. U-shaped casing insertion part 1 provided on the left and right sides of
4 and 14'. Further, the upper casing 10 is formed with an opening 15 that communicates the indoor side 4 and the outdoor side 5, a damper plate section 17 for opening and closing the opening 15, and a Z-shaped structure having a fulcrum 16 on the damper plate section 17. A lever 22 is integrally formed, the fulcrum 16 is rotatably attached to the partition plate 8, and a dogleg-shaped spring 20 is attached to the partition plate 8 and the Z-shaped lever 22. The operating lever 18 is inserted into an opening 19 formed in the partition plate 8. A distal end 18a of the operating lever 18 is adapted to abut a Z-shaped lever 22. 23 is a crank having a support shaft 24 on one side of a flat plate and a moving shaft 25 on the opposite side; the support shaft 24 is rotatably supported at the lower part of the indoor air outlet 26;
The moving axis 25 of No. 3 and the spring 20
The moving shaft 25 is fitted into a wave-shaped recess 27 formed approximately in the center of the operating lever 18 so that the movable shaft 25 slides around the support shaft 24 . 21 is provided with a square hole 28 for positioning the operating lever 18 on the front panel;
The operation lever 18 is held by the square hole 19 of the partition plate 16.

The operation of the damper opening/closing device configured as described above will be explained with reference to FIGS. slides within the wave-shaped recess 27 of the operating lever 18 and moves to the bearing portion 30. Next, as shown in FIG. 7, the operating lever 18 will not move even if the operating lever 22 is pushed any further, so when the external pushing force is removed, the operating lever 18 will be pushed by the force of the spring 20 attached to the Z-shaped lever 22. , the operating lever 18 moves forward and moves to the inclined portion 31 as shown in FIG. 7, and the moving shaft 25 is induced to be locked to the locking portion 32 along the inclined portion 31, and the damper portion 17 is moved forward as shown in FIG. are opened to allow ventilation.

Further, when the operating lever 18 is pressed, the moving shaft 25 moves to the inclined part 33 of the wave-shaped recess 27 and moves along the inclined part 33 to the bearing part 34, as shown in FIG. Even if the operating lever 18 is pushed any further, it will not move due to the crank 23, so if the external pushing force is removed, the sixth
Return to the state shown in the diagram. By moving the operating lever back and forth in this cycle, the damper section can be opened and closed.

[Effect of idea]

As explained above, in this invention, the support shaft of the crank is rotatably supported by the main unit, and the moving shaft of the crank is slidably fitted into the wave-shaped recess formed in the operating lever protruding from the damper.
The locking part and the inclined part provided in this wave-shaped recess and the moving shaft make it possible to easily open and close the damper by pushing the end of the Z-shaped arm. The damper part is pushed directly by the spring, so it can be closed securely. Furthermore, since the number of parts is reduced and assembly work becomes easier, it is inexpensive, operates reliably, and improves operability, among other benefits.
